Tom Cruise has denied reports that his sister is back on board as his publicist.

It was claimed that the Tropic Thunder star has re-hired big sis Lee Anne De Vette to look after his affairs while wife Katie Holmes is busy with work commitments.

Not true, says Tom's reps.

A statement from publicity firm Rogers & Cowan reads, "We at Rogers & Cowan represent Tom Cruise worldwide in the area of publicity and public relations.

"Lee Anne DeVette, who is his sister, is not involved in this area for her brother at all.

"As it was announced three years ago, she remains as his assistant working in areas of his production company that do not include publicity or public relations."

The actor kept his business affairs in the family when Lee Anne took the reigns from Tom’s longtime PR guru Pat Kingsley in 2004.
